Whakataki Waehanga




- P: power supply; I: input; O: output; T: can be set to high impedance.
- GPIO2, GPIO8, and GPIO9 are the strapping pins of the ESP32-C3FN4 chip. During chip power-on and system reset, the strapping pin controls the chip function according to the binary voltage value of the pin. For the specific description and application of the strapping pins, please refer to the chapter on strapping pins in the ESP32-C3 chip manual.
- The power supply mode is Micro-USB interface power supply (default), 5V and GND pin header power supply, 3 and V3 and GND pin header power supply.
ESP32-C3-MINI-1-TB & ESP32-C3-MINI-1U-TB. The main components and connection methods are shown in the following diagram:
